        /* POURQUOI ces deux lignes : la garde ne neutralisait que les
           transitions. Mesure du 2026-08-29 : six des sept déclarations
           d'animation du site jouaient intégralement pour quelqu'un qui a
           demandé l'absence de mouvement — dont le fondu 0,5 s de
           #components-reconnect-modal, rendu par App.razor donc présent sur
           TOUTES les pages, écran de connexion compris.
           animation-iteration-count est indispensable et pas décoratif : une
           animation « infinite » ramenée à 0,01 ms reste une animation qui
           rejoue sans fin, elle tourne simplement plus vite. Trois animations
           du site sont dans ce cas (les deux spinners .loading-console span et
           l'anneau .components-rejoining-animation).
           Effet visible assumé : les spinners se figent. Ils sont dessinés
           comme des anneaux COMPLETS (border sur les quatre côtés,
           border-top-color pour l'accent) animés par un rotate(360deg) sans
           fill-mode : figés, ils reviennent à leur état de départ, un anneau
           entier. Aucune forme tronquée, et le texte reste porté par le
           role="status" qui les accompagne.
